Forex
Forex is trading currency pairs, with no central exchange, open nearly around the clock. High leverage and tight spreads make it risky, not profitable.
Forex trading (short for foreign exchange, also called currency trading) means betting on the relationship between two currencies, quoted as a pair like EUR/USD. If the rate rises, the euro has become more expensive relative to the dollar, nothing more.
What actually moves an exchange rate is mainly the interest-rate gap between the two currencies: capital tends to flow toward whichever currency pays more, which raises demand for the higher-yielding one. On top of that come expectations about central banks' future policy, plus general economic and political factors like growth, trade balances, or political stability. That's why rates often move on announcements and rate expectations alone, before any actual rate change happens.
Unlike a stock exchange, there's no single central marketplace. Trading happens across a decentralized network of banks, brokers, and platforms worldwide, open almost continuously from Sunday evening to Friday evening.
Retail traders almost always access forex through CFDs with leverage. The broker itself is often the counterparty to the trade, not just an intermediary. The spread, the gap between the buy and sell price, is the running cost that hits on every single trade.
Because exchange rates usually move in small percentage steps, brokers advertise unusually high leverage. That same leverage is exactly why small, everyday price moves can wipe out an entire account.
Over the medium term, the exchange rate between two currencies follows, to a first approximation, the interest-rate gap between them: all else equal, capital flows into the higher-yielding currency until the expected return, after accounting for exchange-rate moves, is comparable in both currencies. Because that expectation shifts with every new policy-rate decision and every change in the outlook for future monetary policy, exchange rates often react to central bank announcements and commentary well before any actual rate change happens. Beyond that, broader economic and political factors — growth prospects, trade balances, political stability — shape a currency's underlying attractiveness independent of the current interest-rate gap.
Structurally, the currency market is an interbank market: large banks quote each other prices, brokers source their own prices from that, and pass them on to retail clients with a markup added. There's no single market price the way an exchange has one, there are many slightly different prices from different providers at the same moment.
In the EU, ESMA caps retail leverage on CFDs: at most 30:1 for the most liquid currency pairs, 20:1 for other pairs and gold, less for other commodities and individual stocks. That's a protective measure, not a seal of quality — even at 30:1, a price move of a little over three percent is mathematically enough for a total loss.
Regulated brokers must disclose what percentage of their clients lose money trading CFDs. Those figures, documented in the lesson Loss rates on CFDs, apply structurally to leveraged forex positions just the same, since both are leveraged CFD products with a similar cost structure.
Summary
- Forex is a decentralized market, not an exchange with a single price.
- With CFD forex, the broker is often the counterparty itself.
- High allowed leverage means high risk, not better trading.
Did you get it?
Why does the spread matter so much in forex?
Because it's charged on every trade regardless of outcome, and adds up to one of the biggest cost items for anyone who trades often.
What do ESMA-regulated brokers cap retail leverage at?
At most 30:1 for the most liquid currency pairs, less for other pairs.
Why isn't forex a particularly good place to start trading?
Because high leverage and narrow margins for error leave little room to be wrong, while the market itself is hard to predict.
